HAI - RC-80 Thermostat- How do you disable buttons?


I would like to disable local access/changes to an HAI Omnistat RC-80 thermostat. Physical location is 2nd story. Thermostat will only be used to monitor current/outside temp. Temperature changes/adjustments to be made via console control keypads. I have teenage son that enjoys raising temperature to roasting levels in morning while other members suffer. I believe there used to be a technical bulletin or application note on removing or adding a jumper to board, but can not find when I could use it. Anyone have this helpful info or where located?

Despite what was said in ASA, the HAI panels are just fine alarm panels, but well above the price point for those competing with the "free" systems.

There is a disable local control option in the installation manual for the RC-80, it is not in the user manual. Contact HAI and ask to have the PDF of the manual sent to you. It is indeed jumpering to spots on the PCB.

Check page 9 on your installation manual that says" the keys on the thermostat can be disabled to prevent anyone from controlling the thermonstat locally. To disable the keys, solder a wire jumper across the two holes on the circuit boad as shown below"
